Even as far back as the third century CE, numerous Christians began noticing bible contradictions. They largely accepted these inconsistencies and believed there must be a reason for their existences. What they couldn’t accept, however, was how the early church dealt with these contradictions; the church changed the bible to get rid of them.
Linked in the above paragraph (see chapter XXVII) is a confession by Origen, an early Christian scholar, in which he says that he changed the bible to “answer objections.” He also exposes the “followers of Marcion, and those of Valentinus, and, I think, also those of Lucian” of doing the same. Here we clearly see that 1) early Christians were aware of inconsistencies, and 2) the bible was changed numerous times in order to fix these problems. Of course, they missed countless other contradictions.
Does Origen put Christianity to task for these inherent problems that were whitewashed away? No. Instead he blames people who read the problematic verses and took them to heart, saying that they corrupted the gospels. In other words, because people believed in the problematic verses, those verses had to be erased.
Origen’s actions underscore perfect evidence that the bible is manmade and fallible. If it were not then Origen and his conspirators would not have needed to make any changes to it.
